After Kerik's guilty plea, more secrets slip out

"During the Giuliani Era at DOI," Arsenault told the FBI, according to a memo compiled for the case, "Edward Kuriansky had to inform the Mayor of the details of what was going on at DOI. During this time, Kerik provided details to Kuriansky about the Walker's meeting, and other aspects of what Kerik was involved in, yet no one did anything to look into it further."

The opportune moment to look into it further was in the late summer of 2000, as Giuliani was preparing to name Kerik the city's 40th commissioner of police. But no one did. As was later acknowledged when the Kerik scandal broke full-bore in late 2004, the new commissioner wasn't told to fill out a new background questionnaire, a standard city procedure.

Even at that point, four years later, Interstate was still battling hard to overcome city objections. To help make their case, the DiTommaso brothers hired as their lobbyist one of Giuliani's most stalwart political supporters, former Staten Island Borough President Guy Molinari. As their attorney to testify that they'd cleaned up their act, they brought on another veteran Giuliani loyalist, former deputy mayor Randy Mastro. As a City Hall aide, Mastro had helped create the Trade Waste Commission and served as its first chairman where he helped produce the tough scrutiny that it used on private waste carters. It was all part of the mayor's avowed crackdown on mob influence in the industry.

In December 2004, as the scandal was breaking, the Voice asked Mastro if he'd learned about Kerik's role at Interstate. "At some point, I was told by people at the company," he said. Had he shared that knowledge with Giuliani? "No," he said. "It wasn't an issue that I ever discussed with anyone."

For his part, Kerik is currently under house arrest at home in New Jersey, an electronic ankle bracelet monitoring his movements. He's due to keep it on until his sentencing on February 18 by Judge Stephen Robinson in court in White Plains. Prosecutors have agreed to a prison term of 27 to 33 months. The judge could go higher if he chooses.
